Our best selling bra for a reason.


The most supportive of our wireless bras. Great shape, naturally smoothing, airy light and sexy sheer — Belgian micromesh might just be magic.

    Love!

    I have this in 2 other colors and tried a smaller size this time since I have lost some weight. Had to exchange for my original size but team made it very easy.

    Need one in every color

    The Sieve Non Wire Bra is my favorite. So comfortable and moves with me. Doesn’t roll up. I’m mid-sized and it fits so well. Just bought my second color.
